Abstract: The paper aims to present some new hydropower technologies that use the hidden hydro potential of small and very small head, the investigation of locations with significant hydropower potential such as urban water supply systems, irrigation systems and small rivers in Romania (including small dams and non-energy dams) but also of other possible locations with significant hydropower potential. Even if this hidden hydropower potential is not significant in terms of contribution to the national energy system (SEN), this potential could be useful for reducing electricity......

Abstract: Over the time , recycling has become one of the most adoptable pavement rehabilitation alternatives, and different recycling Procedures are now available to address specific pavement distresses and structural needs . Recently, Industrial wastes have been widely used to improve the properties of asphalt binders due to their unique properties. Cracking and degradation is common mode of failure in asphalt pavements that occurs due to increasing traffic loads or even due to variation in environmental conditions. To overcome these damages, some solutions.....

Abstract: The utilization of Carbon Fiber Reinforced Polymers (CFRP) has exhibited promising results in enhancing the shear capacity of reinforced concrete (RC) beams. The effectiveness of CFRP is contingent upon its bonding properties with the concrete substrate. The Embedded Through-Section (ETS) technique is distinct from the Externally Bonded (EB) and Near Surface Mounted (NSM) techniques, as the latter two employ CFRP sheets or plates that are attached to the concrete cover of RC beams. The ETS method utilizes CFRP bars that rely on the concrete core of the.....

Abstract: Controlling inundation in residential areas is not enough by constructing drainage channels with sufficient dimensions, but it is also necessary to think about how to technically absorb rainwater into the ground so that housing construction does not impact the land or lower areas. For the purposes above, a study on the planning of drainage channels and storage ponds was carried out at the Diamond City Housing Complex, located in Jember Regency. The stages of the study include hydrological analysis to determine the planned flood discharge, hydraulics analysis to design the capacity of the drainage canal, soil permeability analysis to plan water catchment ponds. Based on the results of a study for inundation control at Diamond City Housing, it was found
that the flood discharge that occurred was 0.651 m3/second, the number of drainage channels was 25 sections with 4 storage ponds capable of holding and absorbing water for 2 hours.
